So the battery light has come on 3 times over the last week. The battery gauge is showing 13.3V when running, regardless of lights, AC, radio or engine speed. Voltmeter shows the same and the alternator belt is tight. I'm guessing it is the voltage regulator and where do you suppose FCA put it? Yep, the worst possible place, in the PCM. Made an appointment to get it checked out next week. I am glad I don't have a tune in it. Anybody else ever have this failure yet?
